CARBONATATION-VAT.

SPECIFICATION forming part of Letters Patent No. 659,359` dated October9, 1900.

Application led November 27, 1899. Serial No. 73 8,475. (No model.)

To all whom, it may con/cern:

Be it known that we, EDMUND C. BURR, residing in the city and county ofSan Francisco, JOHN C. H. STUT, residing at Oakland, county of Alameda,and JOHN W. ATKIN- sON, residing at Santa Maria, Santa Barbara county,State of California, citizens of the United States, haveinvented certainnew and useful Improvements in Carbonators for Sugar-Factories; and wedo hereby declare the following to be a full, clear, and exactdescription of the same.

Our invention relates to carbonators in which in sugar-factories thejuice leached ont from the beets in the diffusion-cells is treated withlime and carbonic-acid gas.

In practice the pipes which convey the carbonic-acid gas down into thecarbonationpans become coated with lime and require to be removed. Thisnecessitates the workman getting down into the pan, a dangerousproceeding on account of the presence of the carbonic-acid gas, and asthe pipes are usually arranged they can be removed only with' some painsand the expenditure of enough time to render the immediate getting downinto the pan an impracticable thing. The only way he can go down safelyis after the removal of the gas and the cooling of the carbonator. g

The object of our invention is to provide for the ready removal of thegas-introducing pipes without requiring the Workmen to get into thecarbonator.

To this end our invention consists in a removable cover, pipes carriedthereby and adapted to be removed from the carbonatorpan through thecovereopening with the said cover, and suitable detachable connectionsof said removable pipes with the fixed pipes, all as we shall nowdescribe by reference to the accompanying drawings, in which- Figure lis a sectional elevation of our carbonator. Fig. 2 is a top view ofsame. Fig. 3 is a View of the gas-pipe C, secured in the removablecover. Fig. 4 shows details of the removable fastenings of the cover. f

A is a carbonation-pan of the usual general construction. In its top isa vent a,'also a sight-hole d and the screw-and-nut mechanism a2 foroperating the discharge co3 below through suitable connections a4. Inthe top of the pan is made an opening b, which is covered by a lid orcover B, said cover being secured to its seat by means, such as boltsZ9', which are adapted to be easily released in order to permit thecover to be removed.

C C are pipes which pass down through the lid or cover B into the panand are provided on their lower extremities with perforated branches cfor emitting the gas into the contents of the pan. These pipes C C aremade fast in the cover by suitable means, as by being screwed insections into thiinbles b2 in the cover.

D is the main gas-supply pipe. From it depends a branch d, having ahorizontal portion d below, which communicates through a valve E,operated by handle e, with lateral hanches 612,130 which it is connectedby means of suitable elbows F, the pipes C C being connected to saidlateral branches, as shown. The connections at F are detachable ones, asby angesf with bolts f', and they are so disposed that when the bolts fare removed the pipes C C, with the previously-unfastened cover B, maybe lifted straight up without obstruction until the lower extremities ofsaid pipes are entirely removed from the pan. These extremities-namely,.the discharge branches c-are made of a length to readily permit them topass upwardly through the opening b. To facilitate the lifting of thepipes we have an overhead track or rail G, on which is an eyebolt ortrolley g, from which a hook-chain may pass down to the pipes. When itis required to remove the pipes from the carbonator, the cover B isreleased. Then the flanges fare unbolted and the chain is dropped to itsconnection, and as soon as made the cover B and the pipes C C are liftedbodily from the pan. The cover B isa twopart one, bolted at itsdivisional line by central cross-flanges b3, above which lies thehandle-stem e, so the latter is not in the way. Either part of the covermay be removed independently of the other.

Having thus described our invention, What l we claim as new,'and desireto secure by Letters Patent, is-

l. In combination with a carbonator, a gasihtroducing pipe extendingdown into the carlOO bonator and havingr branches upon iis lower end, aremovable cover for the earbonal or to which said gasinirodueing pipe issecured adapting it to be lifted with the cover, Said covercoveringandadapted to expose an opening: inthe earbonafor of sufficient area topermit the passage of' the gaspipe branches through it, fixed gas-supplypipes, and detachable connections between said ,iras-introducing pipesand the fixed gas-supply pipes, said connections being located to oneside of the vertical plane of the cover whereby the latter may be liftedoff and its attached pipes raised from the carbonator withoutinterference with said fixed gassupply pipes.

2. In combination with aearbonator, a sectional cover therefor, theparts of which are sepa arely removable, gas-introducing pipesdependingr within the earhonatorand passing through and secured one toeach section of the cover, fixed gas-supply pipes, detachableconnections between said pipes and the fixed gas-supply pipes, saidconnections being lo- WVitnesses to the signatures of E.
